The Kitzur Shulchan Aruch brings down a minhag to make three Brachos (Eisvay, Minay, Nosson Reiach tov Lapri) on Smell on Yom Kippur to make up for The Hundred bracha a day Obligation and in some Shuls there is one guy who always brings the Lemon with Cloves stuck in it. What Bracha is made on its smell?

After a Correspondence with Rabbi Belsky he said that the Brocho is Nosson Reiach Tov Lapri.
It seems Reb Yitzchak Yosef agrees(Yalkut Yosef 216:7) as does Ginas Veradim 1:42. But the Ketzos Hashulchan 62:9 in Badei Hashulchan both agree mith Mekubal and say its Minie Bsamin.
